Asia‐Pacific Economic History Review, Volume 66, Issue 2, Page 239-255, July 2026.Abstract New Zealand's early‐twentieth‐century health service was a two‐tier system of state hospitals supported by an expanding network of over 300 private hospitals, almost exclusively owned by nurses and midwives. This article will show that this environment was created by a legislative framework introduced between 1901 and 1906, requiring nurses ...

Variable rate QAM for mobile radio [PDF]
IEEE Transactions on Communications, 1995 Quadrature amplitude modulation (QAM) schemes which vary the number of modulation levels in accordance with the mobile radio fading channel variations are investigated. Important parameters considered are the fading rate and the block size used. We describe how the adaptive QAM modems can be employed and consider their use in a DECT-like TDD packet ...

Plant Pathology, Volume 75, Issue 4, July‐August 2026.Eight Fusarium species are associated with the pumpkin rot in north‐east Brazil. ABSTRACT Pumpkin (Cucurbita) is a cucurbit of great economic and social importance in Brazil. However, fruit rot caused by Fusarium species represents a significant limitation to crop production, compromising quality and hindering commercialisation.

Per Coefficient Filter Optimization for Rectangular and Quincunx QAM-FBMC
IEEE AccessQuadrature amplitude modulation based filter-bank multicarrier (QAM-FBMC) is a promising technology for future wireless communication systems. When we compare QAM-FBMC systems with the classical orthogonal frequency division multiplexing (OFDM), QAM-FBMC

Prenatal Diagnosis, Volume 46, Issue 7, Page 1104-1111, June 2026.ABSTRACT Objective The heterogeneity of fetal surgery has led to variability in the nature and frequency of fetal instability. Understanding these differences is critical for optimizing management. Methods We reviewed all fetal atrial septal interventions (FASI) and fetoscopic myelomeningocele (fMMC) repairs with fetal instability performed at our ...
